INTRODUCTION
Before you begin on your journey, a word of caution.
In the comfort of your own home you are about to assemble a robot. This
machine can maim, burn, and electrocute you if you are not careful. Please
do not become the rst VORON fatality. There is no special Reddit air for that.
Please, read the entire manual before you start assembly. As you begin wrenching,
please check our Discord channels for any tips and questions that may halt your progress.
Most of all, good luck!

HEAT SET INSERTS
This design relies heavily on heat
set inserts. Make sure you have the
proper inserts (check the hardware
reference for a close up picture and
the BOM for dimensions).
If you’ve never worked with heat set
inserts before we recommend you
watch the linked guide.

SET SCREWS
aka the root of all issues
Insert both set screws and use thread
locker on all set screws.
Use a high quality hex driver to prevent
the hex prole from stripping. Ball-end
drivers are not recommended.
Loose set screws account for the majority
of issues that our users report. Save
yourself hours of troubleshooting and
apply thread locker to all set screws
during the build.
See the products application notes for
instructions - keep away from printed
parts.

16 TOOTH PULLEYS
The Z drive motors are the only
place in the printer that use 16 tooth
pulleys!
Remove them from your work surface
after you nish this chapter.
PULLEY POSITION
Depending on your motors,
you may nd that the pulley
sits better in the opposite

thing is the placement of the
actual teeth.
